Product Description

Red phenolic laminate (Bakelite) machining components consist of layered thermosetting phenolic resin reinforced with organic or inorganic fillers. Key components include:

Phenolic resin (30-50%): Acts as the binding matrix, providing thermal stability and electrical insulation.

Fillers: Typically cellulose (wood pulp), cotton fabric, or paper (40-60%), enhancing mechanical strength and machinability. Modern variants may use fiberglass or mineral fillers.

Pigments: Iron oxide (Fe₂O₃) additives create the characteristic red color.

Additives: Lubricants (e.g., graphite) reduce friction; curing agents aid polymerization.

Manufactured under high heat/pressure, the cross-linked resin forms a rigid, non-conductive structure resistant to heat (≤120°C), chemicals, and wear. Composition varies by grade to optimize properties for electrical, mechanical, or thermal applications. Contains no asbestos in modern formulations.

Red phenolic laminate machining components exhibit key properties:

Electrical Insulation: High dielectric strength, ideal for electrical applications.

Thermal Resistance: Stable up to 120°C; avoids deformation under moderate heat.

Mechanical Strength: Rigid structure with good wear resistance; handles machining stresses.

Chemical Resistance: Resists solvents, oils, and mild acids.

Dimensional Stability: Low moisture absorption (<1%) ensures precision post-machining.

Machinability: Smooth cutting with minimal tool wear; retains edge sharpness.

Flame Retardancy: Self-extinguishing (UL94 V-0 rated).

Red phenolic laminate machining parts are widely used in:

Electrical Systems: Insulators, terminal blocks, and switchgear components (high dielectric strength).
Automotive: Distributor caps, gears, and bushings (heat/wear resistance).
Industrial Machinery: Bearings, rollers, guides (dimensional stability, low friction).
Electronics: Circuit board supports, connectors (flame retardancy, precision).
Aerospace: Non-conductive housings, sensor mounts (lightweight, thermal resilience).
Consumer Appliances: Handles, knobs (color retention, chemical resistance).
Tooling: Jigs, fixtures (machinability, durability).
Suitable for high-voltage, high-wear, or temperature-sensitive environments, replacing metals in cost-sensitive applications. Excludes asbestos in compliance with safety standards.
